In order to study the effects of oil contaminated soil on the germination and growth of plant seedling

crude oil and fluvo aquic soil in the oil extraction area of Zhongyuan Oil Field were selected to study seed germination

individual height

and fresh weigh germination under the condition of various oil concentration of soil by the pot planting experiment.Results show that the variation of oil concent ration of soil has different effects on each index of ryegrass

tall fescue

alfalfa

white clover

and red clover growth.Crude oil rest rains growth of them when its content is high.All treatments have less effect on seed germination

in dividual height and fresh weight of sunflower

cotton

Bermuda grass

and sorghum sudanense.They can grow on oil-contaminated soil.Bermuda grass can be fit to grow on the crude oil-contaminated soils by it self and it is a plant with the biggest experimental potential to phytoremediation of oil-contaminated soils in this experiment.
